I'm using TWRP. Tried to flash a ROM, discovered that I didn't have the right requirements. Then I tried to restore a backup of mine that I made prior to flashing the ROM. I wiped all the data and did a factory reset, I fixed permissions, then restored my backup. Restore was successful, and then it said that my device wasn't rooted and asked if I wanted to install SuperSU. I clicked "Install" and now I am stuck on the Samsung Galaxy S4 Boot logo; it won't reboot or anything. I am able to go back into recovery, so I tried the process again but instead hit "Do Not Install" and my phone is still stuck on the Boot logo. Any advice?
